Abstract : Although a number of cross-linkable energetic polymers are known, most are not stable at 150 C either because the energetic moiety (nitrato, azido) is not stable, or because the functional (end) groups are not stable. Polynitroalkyl acrylates can be cross-linked with di-acrylates, but the resulting three-dimensional polymers are hard and brittle and are not suitable for use as binders. It would therefore be desirable to provide an energetic, flexible binder which is suitable for explosive compositions and which has a high degree of thermal stability. Summary of the Invention: Accordingly, an objective of this invention is to provide - a new energetic polymer which is suitable as a binder for explosive composites. Another object of this invention is to provide a new energetic polynitro polyformal polymer which has a hydroxy functionality suitable for cross-linking. A further object of this invention is to provide a new energetic polynitro polymer having improved thermal stability. Yet another object of this invention is to provide a new polynitro homopolymer which has a glass transition point below room temperature.
